Step 2: What you need to do:

>>Hide the Cell phone (optional)If you wish you can have the phone out in the open. (Face down if you phone does not have a display setting.) Say on your desk.

>>Plug in the power cord (optional)If you would like to bug an area for more than a day, then you may want to plug it in...USB if near your computer.Wall Plug if in bedroom, den, or other rooms12v DC if in a car (Have you ever wanted to hear what's going on in your teen's car on Saturday night)

***NOTE***If you wish to bug an area for a week or more you may want to go with a mobile prepaid phone (Alltel, Cingular, Tracfone, Net10, T-mobile, Verizon, Virgin Mobile,or Boost mobile)

If you use Boost in a car you got GPS too.....

Step 3: Now it's time to listen in to the area

Call the cell to listen in on the area where you placed the phone.

After a few rings the cell phone will pick up, just listen in on what's being said.

Cell phone signals tend to disturb car stereo, TV-speakers, Walkman, monitorspeakers etc, so allthough this is a straightforward "hack" it will also be very simple to detect that someone is eavesdropping.

mobile (cell) phone signals only interfere with unshielded equipment. most cars have shielded stereo's so the engine doesn't interfere with them. if you wanted to put the phone somewhere near unshielded equipment then putting the phone in a metal case would stop it interfering with other equipment.

Good post! ...I thought that was only GSM phones? The phone above in the picture looks like the Nokia 2865i, which is a CDMA phone. Also, this works very well with free M2M (mobile-to-mobile, available on most phone plans now) as long as you are calling from a phone on the same network/provider.

i have seen this in a police report (it is Very ilegal to put in somewhere if its not your own car, bus, mcdonnalds,etc :-P) someone has put one of these in a girls suv and used its phone gps system to track her down and eavesdrop her any time the murderer wanted to (murderer was husband :-X) till one day she was killed, and the police found a rig hidden in the console, and was tapped into the suvs power so it would charge forever. cool, but not so cool. :-/

I believe their are laws that address eavesdropping on others. without their knowledge. The reason for the boiler plate message "this call may be monitored,,, " when one calls some customer service numbers.

the cheapest kyosera have those options ive thought of this before and done it for the hell of it no doubt this works . think i should do a instructable i made software that motion detects a room threw a camera & could be done threw a parralel port using a motion sensor then when it detects anything the application opens up gismo 5 and give you a ring you can listen to the room and you can talk threw your pc speakers ...wow that sound like paranoia...but i have alot of roomates and a few things missing.........
